When your heart beats, it squeezes blood into the arteries and creates pressure. The systolic pressure or top number, represents the heart’s force of moving the blood into those arteries. Between beats, the heart is at rest while it refills with blood. The diastolic pressure, or bottom number, measures the pressure in the arteries while the heart is resting.
I totally agree with you that we should not rely on medication for high blood pressure. End of the day, high blood pressure is a symptom that our body requires immediate attention. The kidneys work extremely hard to send out the “signal” to us and what we did is to pop a high blood pressure pill to suppress the signal. With this medication, our body has to work even harder to send us another signal. No wonder over the long run people who are suffering from high blood pressure needs an additional pill for deteriorating kidneys. Our body is fully capable of healing itself without us realizing it. I strongly encourage high blood pressure sufferers to listen to this and say goodbye to high blood pressure once and for all:
Coconut water finds itself high on the list of home remedies for high blood pressure. One of the causes for high blood pressure is an imbalance of electrolytes in the blood. Because coconut water contains an adequate supply of minerals and salts, it can help counter this imbalance. Modern researchers say the potassium content in coconut water plays a huge role in lowering blood pressure. Both potassium chloride (seen in supplements) and potassium citrate (seen in foods) can help lower blood pressure. Potassium helps balance out the level of sodium in your blood and keeps your body functioning properly.
2. Take an omega-3 oil. Omega 6:3 ratio is important. A lot of us get way too much omega-6 in our diets, which is what's caused the omega-3 craze. Refined vegetable oil is one of the main culprits, and found in almost all processed foods, and even some orange juices. Because we have way too much omega-6 in our systems, we need to compensate by taking some form of omega-3 oil. Decreasing your intake of processed foods will have a similar effect.

A study published in the journal Hypertension looked at pistachio consumption and blood pressure. Participants, who had high LDL cholesterol, ate one or two servings of pistachio nuts daily for four weeks. In the end, the lower dose of nuts was better at reducing systolic blood pressure than the higher dose. An increase in the volume of blood pumped from the heart could account for the difference, but it's not entirely clear. Or, pistachio nuts may reduce constriction of peripheral blood vessels.

Most types of exercise: aerobic, weight training, and isometric hand-grip exercises helped patients lower blood pressure, with people doing isometric hand-grip exercises showing the most blood pressure reduction (about 10 percent). This was greater than the benefit obtained from a mild aerobic exercise like walking. However, the researchers speculated that this could be related to the lack of intensity or shorter duration of walking done by the subjects. Some older studies have indicated that intense walking over 35 minutes done regularly confers the same cardiovascular benefits. Comparing various alternative approaches, exercise has some of the strongest evidence out there for lowering high blood pressure. 
CoQ10 is a naturally occurring enzyme. It contains antioxidants that are good for maintaining cardiac health. CoQ10 has been shown to decrease blood pressure and reduces the thickening of the heart muscle (hypertrophy). There are no known side effects of CoQ10 since it naturally occurs in the body. According to the Mayo Clinic, for the treatment of hypertension, take 60-360 milligrams daily for 8-12 weeks.

Cayenne Pepper is probably the fastest way to lower high blood pressure. Cayenne pepper is a powerful vasodilator, which means it helps expand blood vessels and improve blood flow. This effect naturally lowers blood pressure levels by increasing the rate at which blood flows throughout the circulatory system, which in turn takes some of the pressure off arterial walls. Either mix one teaspoon of cayenne pepper with half a cup of lukewarm water or mix two tablespoons of raw organic honey with two teaspoons of cayenne pepper; boil them with eight ounces of water and drink when it is warm. A side note: Be careful how many Scoville Units your cayenne pepper is. I bought mine, 90,000 Scoville Units, and OMG. I thought I was going to breathe fire.
Fish are a great source of lean protein. Fatty fish like mackerel and salmon are high in omega-3 fatty acids, which can lower blood pressure, reduce inflammation, and lower triglycerides. In addition to these fish sources, trout contains vitamin D. Foods rarely contain vitamin D, and this hormone-like vitamin has properties that can lower blood pressure.
